Q: Describe few physiologic reasons of "overdamped" and "underdamped" arterial waveforms?

Answer:

Overdamping results in falsely low systolic and falsely high diastolic pressure.

• aortic stenosis,


• vasodilatation,


• cardiogenic shock,


• sepsis,


• severe hypovolemia

Underdamping results in falsely high systolic pressures and falsely low diastolic pressures

• hypertension,


• atherosclerosis,


• vasoconstriction,


• aortic regurgitation,


• hyperdynamic states such as fever
